Radio Fórmula is a Mexican talk radio network. Founded in 1968, Radio Fórmula programs are broadcast on more than 100 stations in Mexico as well as several stations in the United States, it is the flagship product of Grupo Fórmula, which owns the TeleFórmula cable news network and PM Onstreet, an outdoor advertising firm. Grupo Formula traces its beginnings to 1968, when several Mexico City stations were split from Emilio Azcárraga Vidaurreta’s Radiópolis system. Among these was XEDF-AM 970. By 1984, Radio Fórmula operated five Mexico City stations: 970 AM, 1470 AM, 1500 AM, 103.3 FM and 104.1 FM. On September 19, 1985, Radio Fórmula's headquarters in downtown Mexico City were destroyed by an 8.1 earthquake, which killed several hosts and employees and knocked the AM stations off the air for nearly a month. The network relocated to the Polanco neighborhood in the west part of the city. Journalist Pedro Ferriz de Con, who hosted a morning newscast on XEDF-AM managed to survive and spent over a year hospitalized, whereas Sergio Rod and Gustavo Calderón, morning hosts of XEAI-AM, perished.

In 1987, Radio Formula was relaunched under the management of Rogerio Azcárraga Madero, nephew of Emilio Azcárraga Vidaurreta. This led to the establishment of a program schedule that offered a wide range of programs in news, finances and women’s talk. Among the personalities that have worked for Radio Formula over the years are Jorge Saldaña, Héctor Lechuga, Joaquín López-Dóriga, Maxine Woodside, Paola Rojas and Jorge Zúñiga. In 1994, Radio Fórmula began to expand nationally and created three national networks featuring the programs of their major personalities; this unit is now known as Radio Fórmula Estados. In 2003, Radio Fórmula programming began to be available in the United States, on stations such as KUNX In Ventura County, California. Radio Fórmula is organized into three national networks: the Primera Cadena, the Segunda Cadena, Terecera Cadena and Trion. Official website
